I was attempting to update my home computer to 1903 to test the new Sandbox feature. When I ran the Windows 10 Upgrade Adviser, I hit the following error.
It would be great if this error message showed you what the actual issue was.
Luckily, there is a method to find this out.
Open File explorer and click the View tab. Make sure the check box for Hidden items is selected.
Select This PC, and type *_APPRAISER_HumanReadable.xml in the search box and search the PC for file names that end with this term.
Right click the file that ends with _APPRAISER_HumanReadable.xml and open the file with Notepad.
Press CTRL + F and search for DT_ANY_FMC_BlockingApplication. Look for the value, it should be True.
Press CTRL + F and search for LowerCaseLongPathUnexpanded. The value contains the file path of the program that should be removed or transferred to another drive. (It should be located approximately 28 lines under the DT_ANY_FMC_BlockingApplication).
Make note of the file path listed in the value for LowerCaseLongPathUnexpanded. You can select the file path and copy it to the Notepad by pressing CTRL + C.
Navigate to the file path’s location in File Explorer. (Click in File Explorer’s address bar and press CTRL + V to paste the file path you copied earlier.)
Once you’ve located the blocking.exe file, transfer the file to another drive or Delete the file.
You may also download run this batch file to automatically perform the steps above: https://aka.ms/AppRPS(You should be prompted to download a zip file named AppRPS.zip)
The zip file method is the fastest.
From the output, you can see the problem service. In my case, it’s BattleEye, an anti-cheat system for games.
From here you will be able to remove the problem applications or update the required drivers.
The information for my BattleEye issue can be found here. In my case, I removed BattleEye with the tool here, and reinstalled it again after the upgrade by running the game.
If you have created teams or channels in Microsoft Teams, you likely know this creates Office 365 groups. Many other Microsoft products in the 365/Azure space create Office 365 groups. This is Microsoft’s new group which allows great flexibility across services.
However, if you have ever decided to delete a Sharepoint site or Microsoft Team, you will find you cannot create another team or site in its place. You will receive an error saying this group still exists.
This is because the group was delete as a ‘soft delete’. Meaning it’s sitting in a recycle bin for a number of days until it’s permanently deleted.
You can speed up this process. The easiest way to do this is to connect via Powershell and run the following commands
Run the following command if you don’t have AzureAD installed
Once these commands are completed, you can check Azure Active Directory by going to https://aad.portal.azure.com. Select Azure Active Directory and try to delete it. You will get something like the following. In this case, once the licenses have expired (these we removed 12 hours ago) you will be able to delete the tenancy.

There is an in-the-wild exploit for Microsoft Office. A patch has been released. This exploit has turned up on Virtus Total today.
A remote code execution vulnerability exists in Microsoft Office software when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Office software. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) containing a specially crafted file designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file.
Microsoft has made a bit of a boo-boo this week. Hopefully, you haven’t auto approved patches this week.
KB4041691 and KB4041676 were pushed as delta updates through WSUS. First published on Twitter, but now there is a Reddit thread on the issue https://www.reddit.com/r/sysadmin/comments/75o0oq/windows_security_updates_broke_30_of_our_machines/
If you run into this issue, you will need to boot into WinRE and use DISM to remove the update.
With all updates from Microsoft lately, I recommend you lab them first. Don’t take the risk.
